Abstract
A system for monitoring the amount of refrigerant supplied from a refrigerant tank to a plurality of refrigerant systems comprising a tank valve for connection to a refrigerant tank at a predetermined location. A rack of refrigerant rack lines is routed from the location to the refrigerant systems for connecting the tank valve and refrigerant to the refrigerant systems. Rack valves are disposed in the refrigerant rack lines for controlling the flow of refrigerant through the rack lines to a selected refrigerant system. A sensor for determining the amount of refrigerant supplied from the refrigerant tank to a refrigerant system and recording the supplied amount of refrigerant. The system controller controls the rack valves and tank valve to selectively connect the supply of refrigerant in the refrigerating tank with a selected refrigerant system so that the amount of refrigerant delivered to the refrigerant system is recorded by the system controller.
